Enable non-ready-ttl for pdb-controller
Enable non-ready-ttl for pdb-controller

This updates the pdb-controller to version v0.0.7 which enables support
for removing managed PDBs when the `--non-ready-ttl` flag is set.

See: https://github.com/mikkeloscar/pdb-controller/pull/14

The default ttl is set to one hour, but can be tweaked per cluster via a
config item: `pdb_non_ready_ttl`.
